As informed earlier, the multiwavelentgh campaign of the microquaser
GRS 1915+105 with ASCA, CGRO/OSSE and other observatories will start
from April 17 and last till April 25. Attached below are observation
programs currently fixed.

We again encourage whoever interested to make ground observations in
IR and radio during this period. Both of photometic and spectroscopic
observations would be useful. For details of the campaign and
information of exact ASCA pointing intervals, please contact 
Yoshihiro Ueda (ueda@astro.isas.ac.jp).
